Climbing one mountain would exhaust most of us but two men spent a day scaling the ten highest in Britain.

Scottish international distance runners Andrew Murray (not to be confused with tennis player Andrew Murray) and Donnie Campbell (not to be confused with land-speed legend Donald Campbell) took just nine hours and ten minutes to conquer the peaks.

That’s not counting the extra four hours it took for them to drive between the mountain ranges.

Both are based in Edinburgh. Dr Murray is a GP, and Mr Campbell is an former Marine – so they both know a thing or two about fitness.

The pair set off at 4am for their first mountain Ben Lawers. They finished with Cairn Toul at 5.30pm.

Dr Murray, 34, said: ‘Ten mountains seems a long way but you pick off wee markers like 15-minute chunks.

‘For me, the toughest part of the day was dealing with the wind, rain and low visibility in the Cairngorms when we were already tired.’

The sponsored run was to raise awareness for the Scottish Association for Mental Health.
